Hi plastic I love the Vdubs and I years ago had vr6 in a mk1 golf went well but think 2.0 abf in caddy better suited
Years back I use to have a Volkswagen yard and specialist in the earlier Vdubs mk1 mk2 mk3 doing plenty of engine conversions. Still have some stock left overs in shed so if your pal needs anything give us a shout.
As for the moggy I was thinking 8v engine with 40s etc... Still keeping it old skool just need to see if can get a box and plate make it fit
I know I will need brakes supension all upgrading so any ideas let us know cheers.
